From what I understand, the $1.5 billion is covering Transformers, Springfield, Cabana Bay, Potter 2.0, Jurassic Park, and the 2016 KidZone Redo.
This 55 acres, the WnW transformation, land for the 3rd gate, the 3rd gate itself are from a new different budget.
The fact Uni bought 55 acres along I-Drive is huge. The fact that Uni has taken the first step to expand beyond it's current resorts boundaries is even HUGER!
Uni is on the move.
